" i Application filed June 30, 11383.v (Illfodel.)v

To @ZZ whom, t may concern:

Be it known that I, WILLIAM H. Cox, of`

Virden, in the county of Macoupin and State of Illinois, have inventedVa new and useful Improvement in Gates', and I do hereby declare thatthe followingA is a full, clear, and exact description of the same. v

My invention relates to gates of thatclass adapted to be operated fromthe carriage.

The object of the invention is to provide means more simple yandefficient than any which have heretofore been used for this purpose. y

Thelcading feature `of my invention is a self-reversing device wherebythe same mo` tion of a lever is made to either open. or close the gate;but my invention also includes details of construction wherebythisleading principle iscarried practically into effect. j

In the accompanying drawings, Figure l represents a sideV elevation of.the gate, one post being broken away to show the mechan-` ism. Fig. 2 isan end view with the gate in section. Fig. 3 represents a section online x of Fig. l. Fig. 4 represents atop view of the operating mechanismof the gate,- Fig. 5,

a vertical section on line y y, Fi

i a perspective detail view of the gear.

The gate A is of ordinary construction. It is suspended from a bar, B,by `means of Vsuitable strips, a a, or in any convenient manner.

The bar B is provided on its loweredge with a rack-bar, b, whichrests-'upon a pinion, C,

l having flanges c c, which embrace the 'rack bar and hold it in placeupon the teeth. The rear end of the bar B extends between pulleys d e,one of whichis preferably flanged to guide the bar, which is thussupportedy and moves on the pulleys. e,

Motion is imparted to the bar and gate through the pinion C. Thisvpinion is fixed on a shaft, f, which turns on bearing-pinsg g,

fixed in the posts DD. On the same shaft are set two gears, k la', inthe form of rings, with' ordinary cog-teeth. on their. periphery andpawl-teethl upon their sides near the periphery,the pawl-teeth on thetwo rings facing in opposite directions. Two anges, h h, separated by asuitable space, are fixed to the shaft, and serve to hold the gearsklo/'in position. A slotted plate, E, straddles the shaft `oted inaslot, l, in the shaft f.

g. 3.' Fig. Gis

between the two gears k 7c', and each side of said plate carries arack-bar, m m, one set to mesh with* one of the ring-pinions and onewith the other. These bars are constantly inv gear when in motion, andeach is adapted to` turn the shaft and move the gate, one in closing andthe other in opening direction. Connection is formed between these ringsand the shaft by means of pawls o o, which are piv- The Yends ofthesepawls project past the pawl-teeth of the ring gear, and are adaptedto engage withV them. The other and shorter ends of these pawls orlevers are connected to a bar, 2, by

p pins, and the bar extends in the slot toward and near the other end ofthe slotted shaft.i

Pins 4 4in the bar embrace a collar, q, loose on the shaft. This' collarhas ears 5 5, through which pass rods 6 6, the lower ends of which areheld in a bracket, o. The upper ends are brought together and projectinto an inclined slot in a bracket, t, the vertical arm of which ispivoted on the post. Directly over this bracket is another bracket, u,having a straight slot parallel withthe `shaft, and -the ends of therods project through this slot also. Thus the rocking motion of theIbracket which has the inclosed slot carries the rods back and forth inline parallel with the shaft. This motionr through the collar, pins, andbar, here- FIIICE."

to'fore described, moves the pawl-levers altern nately in and out ofgear. ,The rocking bracket tis ushed, when the gate is near the end of 1its movement, by the suspending straps (any suitable projection maybeused instead) striking the edge of the bracket. As soon as the brackethas thus been shifted to bring the rod into the other end of the slot,the pawl in engagement is thrown out and the opposite pawl thrown intogear. Thus at the end of the movementl of the gate in opening, forexample, the pawl which engages-with the opening-gear k isthrown outandthe pawl of the closing-gear ring k is thrown in, so that any furthermovementof the rack-bar begins at once the closing movement.

The inclosed slot has direct resting-places-at eachend. The plate whichcarries the rackbars extend through a guide, and is connected to leversL L, which are provided with cords 7, whereby the levers may be operatedby a IOO person sitting in a carriage on either side of the gate. Therack-bars descend by gravity, and if one movement of the lever is notsuficient to open or close the gate it may be repeated, as the rods willspring enough to let the pawls slip over the teeth.

Other means may be used to operate the rack-bars than those shown, and Ido not limit myself to the levers shown. Any known equivalent also maybe substituted for the rack-bar and pinions which connect the gate tothe shaft, and the details may be modified in other respects.

I claim as my invention-.

1. In combination with a suspended gate, a shaft, and connection betweensaid gate and shaft, whereby the revolution of the shaft moves the gate,gears loose on said shaft, pawls pivoted to the shaft and adapted toengage alternately with the paWl-teeth on the gears,

said pawls being connected to a shifting meehanism adapted to be movedby they opening and closing of the gate, and means for revolving theloose gears, all substantially as described.

2. In combination with a suspended gate, a shaft, and connectionsbetween said gate and shaft, whereby revolution of the shaft movesthegate, gears loose on said shaft, pawls pivoted to the shaft and adaptedto engage alternately with pawl-teeth on the gears, a connection to aloose collar on the shaft, rods connected to said collar and engagingwith the slots of pivoted and fixed brackets, and means for revolvingthe said gears, substantially as described.

8. The combination, with a gate, of the pinion and rack -bar, the shaftprovided with shifting-pawls, and loose gears having pawlteeth held oncollars on the shaft, a bar connected to the 'shifting devices, operatedby the gate to throw the pawls alternately into and out of connection,and rack-bars adapted to be operated by a lever to move the gears,substantially as described.

4. In combination with the shaft connected, as described, to the gate,the loose gears and their rack-bars, the pawls adapted to engagealternately With pawl-teeth on the gears, the loose collar connected tothe pawls, the rods connecting said collar to a shifting-bracket havinginclined slot, and devices on the gate for striking saidshifting-bracket, all substantially as described.

In testimony whereof I have signed my name to this specification inthcpresence of two subscribing witnesses.

WILLIAM H. COX.
